Intro:

As the chipset of nRF5340 is built by Dual Core structure (net core and application core), we need to proceed the coding and compiling process individually to net core & application core.

After the coding and compiling process done, we could get the separate zephyr.hex file respectively which are used for BLE module FW.

Firmware Development Steps : Code Building / Compiling

Case Study :　

NON-Audio Project

　　nRFConnect SDK V2.1.2

Nordic Example code -“hci_rpmsg” & “peripheral_uart”

Nordic example code of “hci_rpmsg” extracted for coding and we will get zephyr.hex file for net core
Nordic example code of “peripheral_uart” extracted for coding and we will get zephyr.hex file for application core

Step 1. Net core Layer

1a) Activate “Open VS Code” IDE in NCS V2.1.2

1b) Select “Add an existing application” and extract “hci_rpmsg” file moving forward

1c) Click “Add Build Configuration” icon

1d) Select “nrf5340dk_nrf5340_cpunet” and check Nordic boards then Execute “Build Configuration”

1e) zephyr.hex file is successfully generated for net core layer if the coding process is properly executed

Step 2. Application core Layer:

2a) Activate “Open VS Code” IDE in NCS V2.1.2

2b) Select “Add an existing application” and extract “peripheral_uart” file moving forward

2c) Click “Add Build Configuration” icon

2d) Select “nrf5340dk_nrf5340_cpuapp” and check Nordic boards, then Execute “Build Configuration”

2e) zephyr.hex file is successfully generated for application core layer if the coding process is properly executed

Intro: With the ready built code of zephyr.hex file for net core and application core individually, we would like to proceed code flashing into the MDBT53/53V Nordic nRF5340 BLE module.

Ready Built Code Programming Steps

Step1.

Execute nRF Connect >> Programmer > > Open

Step2.

Click “SELECT DEVICE” >> Find icon of “nRF5340 DK” which is detected by the programmer app

Step3.

Click icon of “nRF5340 DK” >> “Erase All” to remove the flash memory from MDBT53/53V BLE Module

Step4.

Click “Add File” to load the net core zephyr.hex and application core zephyr.hex both into programmer

Step5.

Do “Erase & Write ” to execute the flashing process for both zephyr.hex into memory of MDBT53/53V Module.

Step6.

To validate the wireless broadcast of default name “Nordic_UART_Service” from MDBT53/53V Module, please check on the “nRF Connect for mobile” APP and do “Scan device” through your mobile. Once the device name is detected in your mobile , the wireless connection is successfully done.
